Subject [jira] Resolved: (QPID-2086) intermittent federated cluster hangs since r810591
Date Thu, 01 Oct 2009 17:38:23 GMT

     [ https://issues.apache.org/jira/browse/QPID-2086?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Conway resolved QPID-2086.
-------------------------------

    Resolution: Fixed

This is a problem with the read-credit code. AsyncIOHandler::readbuff is occasionally called
with readCredit == 0. This fix changes readbuff to do nothing if readCredit==0. There is an
issue somewhere else however since readbuff shouldn't be called with readCredit==0 in the
first place. 

Committed r820717

> On revision 810590 I can run federated_cluster_test_with_node_failure in a loop for over
100 iterations without any hangs.
> However on revision 810591 the same loop hangs quite easily (generally within 10 runs
or so).
